(Color online) (a) Cross section TEM image of the microstructure for the sample with gold nanocrystals embedded in matrix and (b) XRD patterns of films annealed under various temperature conditions.
(Color online) Typical characteristics of sample Au-800 in semilog scale. The voltage is swept in the direction as follows: .
Device yield comparison for four types of samples to clarify the role of nc-Au and annealing process.
(Color online) Endurance performance of the sample Au-800. More than 100 write-erase cycles is demonstrated. (a) The plot of the current vs the voltage curve for a certain times cycles which varies a little. (b) The currents of HRS and LRS vs the number of switching cycles at reading voltage.
